If you can sell the homes for 20k each, that is a value of $460,000 for the homes, resulting in you having paid $840,000 for the park, meaning $66,240 / $840,000 = 7.8% cap rate for the parkIf you plan to keep all the homes as park owned rentals, your expenses will be a lot higher, your tenant turnover will be a lot higher, and you lose all the powerful benefits of MHPs.  

Is there any benefits and downfalls for choosing one type of model over the other, other than the obvious?

There are also local, state and federal tax incentives for certain properties depending on whether they are on the national registry or just in a historical district.Once you understand the requirements you need to make sure to work with architects and GCs that have experience with these types of projects and the process and documentation required to receive full tax benefits as that is a very specific process. 

We’ve saved up and were planning to pay down the loan and refinance it, likely into a primary residence conventional loan in December-January 2020 (6 months after VA loan refi) and then start renting it out in July 2021 when we move so that we could free up our VA loan benefit for a new primary residence at our new location.

Meanwhile, holding the properties personally allows you to use generally cheaper residential loans, and you don’t have the operating overhead of the LLC, as minimal as it might beThere is no tax benefit to the LLC.

Nice tax benefits. 

Well, then I get in to a pickle because sometimes I'd like to keep the properties but the 1st can call the loan even if I reinstate it and, often, the situation is troublesome with escrowed insurance premiums because I have to pay insurance premiums for which I'm not receiving any real benefit.

See benefits of a non compete agreement as being part of the cost. 

Wrote everything you think can benefit you in managing a mf: tapirs you did on your investment, maybe experience from you day job of managing process/people/payroll.

The affect over time is an encouraging one and it takes some good patience.I'd say a hard "no" to the truck . . . the interest rates on an auto loan is currently less than on an equity loan, so there's no benefit that I can see to choosing the more complex route of using a home equity loan to purchase one.
